Embodiment 2

[0031] Embodiment 2, see attached image 3 The connecting rod 401 is axially fixed with a plurality of annular grooves 401a matched with the fastening screws 403, and the annular grooves 401a are inclined grooves gradually narrowing inward, which have a left side and a right side, The two sides of the left side and the right side form an angle of 120°, and the left side is provided with a left elastic piece 5, and the right side is provided with a right elastic piece 6, and the fastening screw 403 and the left elastic piece and the right elastic piece The pieces are in elastic contact, so that the gravity block 402 can move slightly elastically along the axial direction of the connecting rod 401, so that the force of the scraper on the filter belt is elastic, and a better scraping effect can be achieved.

Embodiment 3

[0032] Embodiment 3, see attached Figure 4 , in this embodiment, the gravity block 402 is not on the connecting rod 401 of the suit, but is screwed on the connecting rod 401, the connecting rod 401 is provided with external threads, and the gravity block 402 is provided with internal threads, and, on the connecting rod 401 is provided with fastening nuts 404 for fastening the gravity block 402 on the connecting rod 401 , two fastening nuts 404 are arranged on both sides of the gravity block 402 .

Abstract

The invention discloses a scraping plate mechanism for a filter. The scraping plate mechanism comprises an installation support, a scraping plate frame rotationally installed on the installation support, a scraping plate fixed on the scraping plate frame, and a gravity pressure-applying device fixedly connected with the installation support, and enables the scraping plate frame to rotate under the action of gravity so as to apply a pressure on the filter cloth of the filter. According to the scraping plate mechanism disclosed by the invention, the scraping plate is acted by the gravity pressure-applying device, so as to scrap the filter cloth; according to the scraping plate mechanism, the structure is simple, the price is low, the scraping effect on the filter cloth is good, and damage is slight.

Description

technical field [0001] The invention relates to the technical field of vacuum filters, in particular to a scraper mechanism for filters. Background technique [0002] Authorized announcement number CN101612805 B. The Chinese invention patent whose authorized announcement date is June 15, 2011 discloses a vacuum-belt press filter. It includes a frame, a vacuum filter assembly, a press assembly and a filter belt assembly, and the filter belt assembly includes an upper filter belt, a lower filter belt, and a cleaning device A and a cleaning device B for cleaning the upper filter belt and the lower filter belt respectively, The cleaning device B also includes front and rear guide rollers in the direction of movement of the lower filter belt, the front guide roller is arranged on the top of the lower filter belt and is in close contact with the lower filter belt, and makes the lower filter belt form a V shape, and the rear guide roller is set Below the lower filter belt, there a...
